* Dimensions reflect effective height

 

 

To determine the chimney components needed to complete your particular installation, follow the steps below:

Determine the total vertical height of the fireplace installation. This dimension is measured from the base of the fi replace assembly to the point where the smoke exits the termination cap.

Subtract the effective height of the fireplace assembly from the overall height of the fi replace installation (measured from the base of the fireplace to the bottom of the termination cap).

Refer to Table 5.1 to determine what components must be selected to complete the fi replace installation.

Determine the number of fi restop spacers, stabilizers, roof flashing, etc. required to complete the fireplace installation.
